I definitely wanna check your new ride out tho here soon
word... i have to go up to Owasso with a few racing jugs to fill up.

most people here probably won't have this issue, but I experience vapor locking when running e85 due to heat soaking. I have a small issue with it on 91 and it's very annoying on e85. Once I convert to a return style system it should be resolved.

Of course it was 102 degrees today which really makes the issue bad.

Yup, 740 AVERAGE rwhp, figure another 20-50 for peak hp + drive train loss = 900ish hp.

well the car is runing and I have all the normal driving map dead on..... HOWEVER. The car just turns off once it gets close to boost. It falls on its face and then does not recover until you back off a little. The only way I can sustain boost is to put it in first, take it to 2500 rpm and then press it down. It still does not run the best, but it will go to 9psi like right now. as soon as it goes to 2nd, it falls like I lt off of the fuel. The data logs show the timing and eq to be good. 1.3 eq. If anybody is intrested in helping me send a good report to Tiff, here is the post I made on the tuning site. .it has the tune and data log for efilive... I will try anyting.

My only experience is with Hp Tuner's but, why do you keep mentioning the EQ? If it is the same as HP that table is just the commanded a/f. if the tune is not right it can show your eq correctly and the fuel be way off. What is the air-fuel, assuming your using a wideband?

I have converted everything to EQ since I am running e85. both commanded "AFR" and WB "AFR" are set to read EQ instead of AFR. However, to convert to AFR i am runnng about 7.5 Actual AFR (e85 calculation) and 11.03 (petro calculation) at wot and above. With this in mind, it is easer to read everything in relation to stoic. Also 0 to 5 volts, 10 to 20 afr I am reading .75 volts, which is 11.03 petro, 7.5xx E85, 1.3xx EQ.

Cool.. thanks for the response.
